Si86xx 1 Mbps Data Sheet
1 Mbps, 2.5 kVRMS Digital Isolators
Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering sub-
stantial data rate, propagation delay, power, size, reliability, and external BOM advan-
tages over legacy isolation technologies. The operating parameters of these products
remain stable across wide temperature ranges and throughout device service life for
ease of design and highly uniform performance. All device versions have Schmitt trigger
inputs for high noise immunity and only require VDD bypass capacitors.
All products support Data rates up to 1 Mbps and Enable inputs which provide a single
point control for enabling and disabling output drive. All products are safety certified by
UL, CSA, VDE, and CQC and support withstand ratings up to 2.5 kVRMS.
Automotive Grade is available for certain part numbers. These products are built using
automotive-specific flows at all steps in the manufacturing process to ensure the robust-
ness and low defectivity required for automotive applications.

Ordering Guide
1. Ordering Guide
Industrial and Automotive Grade OPNs
Industrial-grade devices (part numbers having an “-I” in their suffix) are built using well-controlled, high-quality manufacturing flows to
ensure robustness and reliability. Qualifications are compliant with JEDEC, and defect reduction methodologies are used throughout
definition, design, evaluation, qualification, and mass production steps.
Automotive-grade devices (part numbers having an “-A” in their suffix) are built using automotive-specific flows at all steps in the manu-
facturing process to ensure robustness and low defectivity. These devices are supported with AIAG-compliant Production Part Approval
Process (PPAP) documentation, and feature International Material Data System (IMDS) and China Automotive Material Data System
(CAMDS) listing. Qualifications are compliant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, de-
sign, evaluation, qualification, and mass production steps.
